High Volume Oil Pumps
Advantages, Myths and Fables
Most stock automobile engines are designed to operate from idle to 4500 RPM. The original volume and pressure oil pump will work fine in this type of application. But, as the demands on the engine increase, demands on the oiling system and pump increase as well.

The Oil Pump's most difficult task in to supply oil to and connecting rod bearing that is the farthest from the pump. To reach this bearing, the oil travels form three to four feet, turns numerous square corners through small holes in the crankshaft to the rod bearing. The rod bearing doesn't help matters. It is traveling in a circle which means centrifugal force is pulling the oil out of the bearing.

The size of the gears or rotors determines the amount of oil a pump can move at any given RPM. Resistance to this movement creates the pressure. If a pump is not large enough to meet the demands of the engine, there will not be any pressure. Or if the demands of the engine are increased beyond the pumps capabilities there will be a loss of oil pressure. This is where the HIGH VOLUME pumps come in; they take care of any increased demands of the engine.

Increases in the engine's oil requirements comer from higher RPM, being able to rev faster, increased bearing clearances, remote oil cooler and/or filter and any combination of these. Most HIGH VOLUME pumps also hand an increase in pressure to help get the oil out to the bearings faster.

Now that we've gone over what a HIGH VOLUME pump will do, here's a couple things it won't:
1) It will not replace a rebuild in a worn-out engine. It may increase pressure but the engine is still worn out.
2) It will not pump the oil pan dry. If a pan is pumped dry, it is because the holes that drain oil back to the pan are plugged. If the HIGH VOLUME pump is also higher pressure, there will be a slight increase in flow to the top.

High Volume pumps can be a big advantage if used when needed. If installed in an engine that does not need the additional volume, they will not create a problem. The additional flow will be re-circulated within the pump.
